In the payload bay of the orbiter Discovery, STS-103 Mission Specialists John M. Grunsfeld (Ph.D.), left, and Claude Nicollier of Switzerland, right, are briefed on part of the equipment they will use on their mission by a worker from Johnson Space Center, center. The mission involves the repair and upgrade of the Hubble Space Telescope. The crew, who are at KSC to take part in a Crew Equipment Interface Test, also includes Commander Curtis L. Brown Jr., Pilot Scott J. Kelly, and Mission Specialists Steven L. Smith, C. Michael Foale (Ph.D.), and Jean-François Clervoy of France. Nicollier and Clervoy are with the European Space Agency. Mission STS-103 is a "call-up" due to the need to replace portions of the pointing system, the gyros, which have begun to fail on the Hubble Space Telescope. Although Hubble is operating normally and conducting its scientific observations, only three of its six gyroscopes are working properly. The gyroscopes allow the telescope to point at stars, galaxies and planets. The STS-103 crew will not only replace gyroscopes, it will also replace a Fine Guidance Sensor and an older computer with a new enhanced model, an older data tape recorder with a solid-state digital recorder, a failed spare transmitter with a new one, and degraded insulation on the telescope with new thermal insulation. The crew will also install a Battery Voltage/Temperature Improvement Kit to protect the spacecraft batteries from overcharging and overheating when the telescope goes into a safe mode. The scheduled launch date in October is under review

JOHNSON SPACE CENTER, Houston --- STS124-S-001 --- The STS-124/1J patch depicts the Space Shuttle Discovery docked with the International Space Station (ISS). STS-124/1J is dedicated to delivering and installing the Japanese Experiment Module (JEM) known as Kibo (Hope) to the ISS. The significance of the mission and the Japanese contribution to the ISS is recognized by the Japanese flag depicted on the JEM Pressurized Module (JPM) and the word Kibo written in Japanese at the bottom of the patch. The view of the sun shining down upon the Earth represents the increased "hope" that the entire world will benefit from the JEM's scientific discoveries. The JPM will be the largest habitable module on the ISS and is equipped with its own airlock and robotic arm for external experiments. In addition to delivering and installing the JPM, the STS-124 crew will relocate the JEM Logistics Pressurized (JLP) module to its permanent home on the zenith side of the JPM. During three planned space walks, the crew will perform external ISS maintenance and JPM outfitting, as well as extensive robotic operations by the ISS, space shuttle, and JEM robotic arms. It will be the first time that three different robotic arms will be operated during a single space flight mission.

At the Shuttle Landing Facility, STS-97 Mission Specialist Joseph Tanner (left) is greeted by Center Director Roy Bridges on his arrival at KSC from Johnson Space Center. Tanner and the rest of the crew have returned to KSC for the launch, scheduled for Nov. 30 at about 10:06 p.m. EST. Mission STS-97is the sixth construction flight to the International Space Station. Its payload includes the P6 Integrated Truss Structure and a photovoltaic (PV) module, with giant solar arrays that will provide power to the Station. The mission includes two spacewalks to complete the solar array connections. STS-97 is scheduled to launch Nov. 30 at about 10:06 p.m. EST

STS-85 Mission Commander Curtis L. Brown, Jr., poses in his T-38 jet trainer after landing with his crew at KSC’s Shuttle Landing Facility from NASA’s Johnson Space Center to begin Terminal Countdown Demonstration Test (TCDT) activities for that mission. The TCDT includes a dress rehearsal of the launch countdown. The STS-85 mission is now targeted for Aug. 7. The primary payload aboard the Space Shuttle orbiter Discovery is the Cryogenic Infrared Spectrometers and Telescopes for the Atmosphere-2 (CRISTA-SPAS-2). Other STS-85 payloads include the Manipulator Flight Demonstration (MFD), and Technology Applications and Science-1 (TAS-1) and International Extreme Ultraviolet Hitchhiker-2 (IEH-2) experiments

JOHNSON SPACE CENTER, HOUSTON -- STS123-S-001-- STS-123 continues assembly of the International Space Station (ISS). The primary mission objectives include rotating an expedition crew member and installing both the first component of the Japanese Experimental Module (the Experimental Logistics Module - Pressurized Section [ELM-PS]) and the Canadian Special Purpose Dexterous Manipulator (SPDM). In addition, STS-123 will deliver various spare ISS components and leave behind the sensor boom used for inspecting the shuttle's thermal protection system. A follow-on mission to ISS will utilize and then return home with this sensor boom. A total of four spacewalks are planned to accomplish these tasks. The mission will also require the use of both the shuttle and ISS robotic arms. STS-123 will utilize the Station-Shuttle Power Transfer System to extend the docked portion of the mission to 11 days, with a total planned duration of 15 days. The crew patch depicts the space shuttle in orbit with the crew names trailing behind. STS-123's major additions to ISS (the ELM-PS installation with the shuttle robotic arm and the fully constructed SPDM) are both illustrated. The ISS is shown in the configuration that the STS-123 crew will encounter when they arrive.

JOHNSON SPACE CENTER, Houston - The STS-114 patch design signifies the return of the Space Shuttle to flight and honors the memory of the STS-107 Columbia crew. The blue Shuttle rising above Earth’s horizon includes the Columbia constellation of seven stars, echoing the STS-107 patch and commemorating the seven members of that mission. The crew of STS-114 will carry the memory of their friends on Columbia and the legacy of their mission back into Earth orbit. The dominant design element of the STS-114 patch is the planet Earth, which represents the unity and dedication of the many people whose efforts allows the Shuttle to safely return to flight. Against the background of the Earth at night, the blue orbit represents the International Space Station (ISS), with the EVA crewmembers named on the orbit. The red sun on the orbit signifies the contributions of the Japanese Space Agency to the mission and to the ISS program. The multi-colored Shuttle plume represents the broad spectrum of challenges for this mission, including Shuttle inspection and repair experiments, and International Space Station re-supply and repair.

JOHNSON SPACE CENTER, Houston - STS130-S-001 - The STS-130 patch was designed by the crew to reflect both the objectives of the mission and its place in the history of human spaceflight. The main goal of the mission is to deliver Node 3 and the Cupola to the International Space Station (ISS). Node 3, named "Tranquility," will contain life support systems enabling continued human presence in orbit aboard the ISS. The shape of the patch represents the Cupola, which is the windowed robotics viewing station, from which astronauts will have the opportunity not only to monitor a variety of ISS operations, but also to study our home planet. The image of Earth depicted in the patch is the first photograph of the Earth taken from the moon by Lunar Orbiter I on August 23, 1966. As both a past and a future destination for explorers from the planet Earth, the moon is thus represented symbolically in the STS-130 patch. The Space Shuttle Endeavour is pictured approaching the ISS, symbolizing the Space Shuttle's role as the prime construction vehicle for the ISS.

JOHNSON SPACE CENTER, HOUSTON, TEXAS -- EXPEDITION FOUR INSIGNIA -- The International Space Station (ISS) Expedition Four crew patch has an overall diamond shape, showing the "diamond in the rough" configuration of the Station during expedition four. The red hexagonal shape with stylized American and Russian flags represents the cross-sectional view of the S0 truss segment, which the crew will attach to the U.S. Lab Destiny. The persistent Sun shining on the Earth and Station represents the constant challenges that the crew and ground support team will face every day while operating the International Space Station, while shedding new light through daily research. The green portion of the Earth represents the fourth color in the visible spectrum and the black void of space represents humankind's constant quest to explore the unknown.
